Great work here! made it extra challenging for myself by not writing down the information but I did have a system that did help me out. The music was really nice, I really enjoyed the song played during the credits. A change I would have done is having the portals be distinguishable, however, I know that was your intent here. It's a personal preference where I would have wanted the player to solve the puzzle rather than guess it. Overall, really enjoyable. Great work everyone!
